(ALL TIMES ET)

8PM | ABC – 3RD SEASON PREMIERE
Shark Tank – Love this show! Mark Cuban, he of the NBA champion Dallas Mavericks, in onboard for the new season, and will use his NBA-team-owning skills to help ferret out new entrepreneurs, including, in tonight’s season opener, a pitch from NBA Hall of Famer Bill Walton, who teams with triathlete Dave Meyer to pitch a new water bottle business. Other projects pitched to the sharks: a celebrity ghostwriting business and an online funeral-planning business.

8PM | NBC
Chuck – Penultimate episode, which is sad because it was once a great show, and sad because it has definitely not been one in its final season. The lame Nicholas Quinn storyline continues to play out and takes Sarah and Chuck to Japan, while John Casey has to make a potentially life-changing decision.

9PM | FOX
Fringe – Peter’s still on the other side, where the alt-Fringe gang is faced with a serious new enemy.

9PM | NBC
Grimm – Monroe gets an upsetting massage from the creatures. Oops, make that message from the creatures … message. Totally different storyline that would have been.

9:30PM | HBO – SERIES PREMIERE
On Freddie Roach – The new reality series revolves around the titular Roach, a boxing trainer – now dealing with Parkinson’s – who operates from the Wild Card Boxing Club in Hollywood. Filmmaker/actor Peter Berg directs the show, which covers Roach’s days as a boxer (which led to his Parkinson’s) all the way through his standing as the world’s top boxing trainer (Manny Pacquiao is among his clients).

10PM | IFC
Portlandia – While Candance and Toni hold a book signing event, Irys and Spyke plan a wedding that will be anything but cookie cutter.

10 and 10:30PM | CMT
Swanderosa – The Swan family live on a big Texas ranch, where they plan and host big, fancy weddings. Get it? Swans … they live on a ranch … like the Ponderosa … Swanderosa.

10:30PM | IFC
The Increasingly Poor Decisions of Todd Margaret – Todd mistakes a teddy bear for Alice’s ex-boyfriend. Oh yeah, he’s in the hospital and under a big dose of morphine at the time.

Worth flipping to during commercials:
– New America’s Most Wanted on Lifetime (9PM);
– On Girls Who Life Boys Who Like Boys (9PM, Sundance), things go well enough at Olivia’s big charity event, but then … drama;
– On Man Caves (9PM, DIY), a New Yorker who’s far from home wants a den that reminds him of a swanky NYC lounge.
